When upgrading your windows, you’re likely to come across a myriad of technical terms and metrics. One of these crucial metrics is the solar heat gain coefficient (SHGC). This rating plays a pivotal role in determining the energy efficiency and overall performance of your windows.
In this post, we discuss what the SHGC rating entails and why you should ensure your windows have appropriate SHGC ratings.
What Is SHGC Rating?
The SHGC rating measures the amount of solar radiation that enters your home through the windows. It indicates the window’s ability to block heat from the sun, which can have a significant impact on your indoor temperature and energy consumption. The SHGC rating is expressed as a number between 0 and 1, with lower values indicating better heat-blocking capabilities. Numerous factors can affect SHGC ratings, like the type of glazing on the glass or whether the window has any coatings.
What Is a Good SHGC Rating?
What constitutes a good SHGC rating largely depends on your climate. If you live in a colder area, a higher SHGC rating could be beneficial as it lets in more heat from the sun, contributing to a warmer home in winter. However, if you’re in a hotter climate, you’d want a lower SHGC to keep out that extra solar heat and keep your home cool. Generally, a rating between 0.25 and 0.40 is a safe bet, but always consider your local weather patterns for the best choice.
Benefits of Windows With Ideal SHGC Ratings
Opting for windows with a good SHGC rating offers numerous advantages. A lower SHGC means reduced heat from the sun entering your home. It enhances indoor comfort without overworking HVAC systems, resulting in lower cooling costs. Additionally, it mitigates fading of furniture and artwork caused by excessive sunlight exposure.
Improved SHGC ratings also contribute to environmental sustainability by decreasing greenhouse gas emissions. With enhanced insulation and energy efficiency, these windows promote a more comfortable living environment while simultaneously lowering energy bills and fostering eco-friendly practices.
